Help screen toolbar icon Fix
From Joomla! Documentation
- Fix. This program attempts to fix any database table structure problems found in the Database check. It runs any database schema change scripts (from the folder
administrator/components/com_admin/sql/updates
) that were not run during the version update. It then re-checks whether or not the database is up to date. If it is successful, the message "Database table structure is up to date" will show.
